Hello,
Most of my apartment is covered with gypsum fiberboard. I will apply a vapor-permeable primer on top of that, followed by a vapor-permeable fine-texture plaster (lime-based), and finally, it will be painted.
I want the paint to be vapor-permeable as well, so does that mean I should use a lime-based paint?
The goal is for the gypsum fiberboard to be able to absorb some indoor moisture. I don’t want to create a vapor barrier.
Are standard paints the right choice here, like basic white, or do I need something different?
For example, I have read that anti-mold paint is basically just lime-based paint.
The color should be white or matte white.
What would you recommend?
If possible, I’d prefer a paint that only needs one coat. The fine-texture plaster is already nearly white enough to leave as is. I just want to apply a final coat.

Plant casein is used as a primer on drywall panels for lime and clay plasters, but always in combination with reinforcement (such as fiberglass); otherwise, cracks may develop.
By the way, most lime plasters contain additives that are not always as healthy as lime itself. There are very few brands that definitely contain no additives.
I am currently gathering information and offers on this topic and would be happy to exchange experiences!

If I remember correctly, that is a primer, and yes, it tends to seal rather than open up. But doesn't that contradict your goal of vapor permeability? I still don’t quite know how to apply the topcoat to my walls...

garfunkel17 Oct 2019 16:16I have an older building that isn’t really vapor permeable anyway. So the last millimeter on the wall doesn’t make much difference.
Also, not all of the walls are exterior walls.
I’m not even sure if there is such a thing as a vapor-permeable deep primer at all?
